Credit: PixaobayMethamphetamine intake triggers heightened activity in the brain, resulting in a swift surge of dopamine and various neurotransmitters. This induces temporary euphoria, including sensations of invincibility, intense pleasure, heightened motivation and energy, and other psychoactive impacts. Meth is a highly addictive substance, contributing to the demise of brain cells, particularly neurons, and causing...
The first part(a) talks bout different ways electrodes are set up for deep brain stimulation (DBS). There are dark grey areas on the electrodes that can send electric signals. These electrodes can be designed with different spaces between them and different numbers and shapes. If the spaces between them are bigger, they can...
Neurons. Credit: Unsplash.A research team from the University of Lausanne (UNIL) and the Wyss Center has uncovered a novel class of brain cells that plays a pivotal role in brain function. These cells, possessing hybrid characteristics between neurons and glial cells, are found in various brain regions in mice and humans, offering unique insights into memory,...
A recent study indicates that probiotics may improve cognitive function and potentially prevent age-related cognitive decline by modulating the gut microbiome. Particularly in individuals with mild cognitive impairment, shifts in gut microbiome composition, such as decreases in the abundance of Prevotella bacteria, correlated with improved cognitive scores.

"What we do frequently becomes easier not because the nature of the task changes, but because our ability to do it increases." Unknown Author.Fasting is a millenary activity. Exercised by several people worldwide. We may assume that all religions around the globe practice a certain kind of fast and that its benefits for the...
The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS. Credit:https: //www.hopkinsmedicine.org/The Brain has the ability that makes us read, play...

Human and mouse neurons became connected via synapses. Credit: Giovanni Cancemi/Shutterstock.comThink of if lost, deteriorated, or diseased brain parts could be regrown in the laboratory and transplanted for a new lease on life. Scientists at the University of California San Diego have gotten us closer to that fact. Human cortical organoids (or 'mini-brains') transplanted...
Much of the electrical activity in the brain looks like noise and is not associated with reactions to any particular stimuli. The scientists found that there was structure in the noise that could reveal the state of attentiveness in the brain. In this model of brain activity in the monkey visual cortex, the overall...
DETI mapping results from the brain of a person viewing one of the stimuli used in the experiment (far left). The central column shows a flattened topographical map of the electrodes over the back of the head, illustrating the variation of DETI maps at each electrode across that scalp region. On the right-hand side,...
